#
# Description:
# Verify large blocks and redacted send work correctly together.
#
# Strategy:
# 1. Create a dataset and clone with a 1m recordsize, modifying a few k
#    within the first 1m of a 16m file.
# 2. Verify that the whole first 1m of the file is redacted.
# 3. Receive an incremental stream from the original snap to the snap it
#    was redacted with respect to.
# 4. Verify that the received dataset matches the clone
#
